Our Work
The Mystic River Watershed Association (MyRWA) builds solutions so that all people across the watershed, no matter who you are or where you live, have safe and easy access to nature and a healthy environment. MyRWA is rooted in science and the understanding of environmental injustices. We believe access to information and opportunities to learn about the natural world empower us all to work together for a better future in the Mystic. Explore our programs:
MyRWA wishes to honor and acknowledge the indigenous communities native to this region and its past, present, and future. To our knowledge, the watershed is on the colonized lands of the Massachusett, Nipmuc, and Pawtucket tribes. The name “Mystic” comes from the term that these tribes used for the river — “Missi-Tuk,” which means “great tidal river.” As you explore the watershed, we encourage you to learn with us about its past and current indigenous heritage.
